About RunWebTools

RunWebTools is a growing collection of small, focused web tools — formatters, converters, encoders, generators, and text utilities — built to be fast, free, and genuinely useful. No accounts, no installs, no clutter: open a tool and start working.

What you'll find here

Every tool does one job well and loads instantly. Our current lineup includes utilities such as a JSON formatter and validator, a word and character counter with reading-time estimates, and a case converter that outputs nine common styles at once — with more being added regularly across these categories:

• Formatters — beautify and validate code and data.
• Converters — convert between formats and units.
• Encoders & decoders — encode and decode text and data.
• Generators — create IDs, hashes, and placeholder data.
• Text tools — transform, count, and clean up text.

Two ways to use every tool

Each tool works as a normal web page, but most also come as a bookmarklet you can drag to your bookmarks bar. Click it on any website and the tool opens as a small panel right there — handy for formatting or counting text without leaving the page you're on. The panel can be moved to any corner, tucked away to the side, and it remembers where you left it.

Privacy by design

Wherever possible, our tools run entirely in your browser. The data you paste or type is processed on your own device and is not uploaded to a server. Preferences — like your chosen indentation or the order of your favourite options — are saved locally in your browser so the tools feel familiar next time, and never leave your machine. See our Privacy Policy for the details.

Fast and free

Speed matters, so we keep pages lightweight and do the work on the client instead of round-tripping to a server. To keep RunWebTools free for everyone, we display ads. That advertising revenue is what pays for the site and lets us keep building new tools without charging or putting anything behind a login.

Why we built this

Everyday development and writing tasks shouldn't require installing software or trusting a sketchy website. RunWebTools aims to be a reliable, no-nonsense home for the small utilities you reach for again and again.
